No doubt that Walter or HsV will turn in superior times with the manual over the tip on the track...on a dry track.
But on a wet track, the network and the tips integration with the various sensors that allow it to redistrubute power in real time to optimize traction and eliminate wheel slip will prove to be superior.
And in the hands of a amateur driver, the tip is probably faster than the manual at the Ring dry or wet. So you see it has its reasons and capabilities, like it or not neither Porsche and RC are pulling your leg about this.
Maybe if you had more experience at driving 120% fast over slippery surfaces like dirt, gravel and snow the network Tip would be apparently logical to you.
So try to keep in mind that the LSD on the manual car is only for the rear, while the Tip car goes one step beyond and automatically compensates for and instantly redistributes power wheel by wheel when sensing reduced traction at any of the four wheels. Simple, they cannot
integate the mechanical LSD with the network.
A similar system was banned in F1, well now you can have that but you have to give up the clutch pedal to get the complete benefit from it.
You should really crawl on your knees to thank the ex rally driver who has been explaining this simple concept to you all over and over again.
It is really easy to understand.
